Logs saved in the electronic device can be later sent to an external device such as a server and analyzed to investigate whether there has been unauthorized access or unexpected operations by the operator. Patent Document 1 mentioned above describes a technique for preventing erroneous changes of setting items by an operator.

If an event such as unauthorized access or an unexpected operation by an operator occurs, it is preferable to notify the administrator or the like as soon as possible, if possible. To achieve this, improve the firmware, set search conditions for detecting logs that indicate events such as those described above, and detect logs that match the search conditions (for example, logs indicating unauthorized access). Then, there is a method of notifying the pre-registered contact to that effect, but there is a problem of increased labor and cost.

In addition, the event that the manufacturer considers to require notification and the event that the user needs to notify do not necessarily match. Therefore, if there is a request from the user, further modification of the firmware is required, further increasing the cost.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to enable a user to quickly notify an administrator or the like when an event requiring notification occurs on the user side.

When logs stored in an electronic device such as an image forming apparatus are managed using a general-purpose database, a database language such as SQL is used to access the logs. Therefore, if a user can freely create an SQL syntax or the like on an electronic device and increase the number of detection targets as desired by the user, it will be possible to detect logs that do not meet product specifications. That is, it becomes possible for the user to detect an event that requires notification.

An electronic device according to an aspect of the present invention includes a log storage unit that stores a log, a communication unit that performs data communication with an external device, a display unit, an operation reception unit that receives an instruction input from a user, and the log storage. A user is provided with a work environment via the display unit for creating a search formula for the logs stored in the unit and for entering contact information corresponding to the search formula , a working environment providing unit that receives the contact information; a work environment providing unit that receives the contact information; a search formula storage unit that associates and stores the contact information input by the user ; a determination unit that determines whether or not the log matches one of the search conditions ; When receiving, via the operation receiving unit , a notification unit that notifies a contact address registered in advance in association with the search formula to that effect, and an instruction to store the search formula in the search formula storage unit a judgment unit for judging whether or not the search formula includes a predetermined character string that enables editing of the data stored in the log storage unit; and a prohibition unit that prohibits storage of the search formula including the predetermined character string in the search formula storage unit when it is determined that the character string is included.

Further, an image forming apparatus according to one aspect of the present invention includes the electronic device described above and an image forming section that forms an image on a recording medium.

According to the present invention, when a log that matches the search conditions of a search expression (for example, SQL syntax) created by a user is detected, a pre-registered contact (for example, an administrator) is notified to that effect. . In other words, even if the search conditions are not prepared in advance by the manufacturer of the electronic device, it is possible to detect the log corresponding to the search conditions created by the user. In addition, since the above notification is sent directly from the electronic device without going through a server or the like, when an event requiring notification occurs on the user side, it is possible to quickly notify the administrator or the like of that fact.

When the control unit 100 stores a log indicating an event that has occurred in the log storage unit 112 (S1), the determination unit 103 reads out the search formula stored in the search formula storage unit 113 (S2), and stores the log in S1. It is determined whether or not the log saved in the saving unit 112 matches any of the search conditions of the read search formula (S3). However, the search formula read out by the determination unit 103 in S2 is set to "ON" on the operation screen G6 shown in FIG. is limited to search expressions that

If the determination unit 103 determines that the log matches any one of the search conditions (YES in S3), the notification unit 104 sends the notification destination address stored in association with the search expression indicating the search condition. Then, the subject is read out from the search formula storage unit 113 (S4), and an email is sent via the network interface unit 91 with the read subject attached to the read notification destination address (S5), and this process is terminated.

On the other hand, if the determination unit 103 determines that the log does not match any of the above search conditions (NO in S3), this process ends.

According to the first embodiment, when a log that matches the search conditions of a search expression (for example, SQL syntax) created by a user is detected, a pre-registered contact (for example, an administrator) is notified to that effect. be notified. In other words, it is possible to detect a log corresponding to a search condition created by a user without using a search formula prepared in advance by the manufacturer of the image forming apparatus 1 . Further, since the notification is directly performed from the image forming apparatus 1, when an event requiring notification occurs on the user side, it is possible to quickly notify the administrator or the like of the fact.

Further, since the determination by the determination unit 103 as to whether or not the log matches the search condition is performed at the timing when the log is stored in the log storage unit 112, events such as unauthorized access and unexpected operations by the operator may occur. When this occurs, it is possible to immediately contact an administrator or the like.

However, as another embodiment, instead of the timing at which the log is saved in the log storage unit 112, at the timing at which a predetermined amount of logs are accumulated in the log storage unit 112, or at each predetermined fixed period, The determination unit 103 may make the above determination.

FIG. 12 is a functional block diagram schematically showing the main internal configuration of an image forming apparatus as electronic equipment according to the second embodiment. An image forming apparatus according to the second embodiment differs from the image forming apparatus shown in FIG. It is the same as the image forming apparatus 1 concerned. The control unit 10 further functions as a determination section 105 and a prohibition section 106 through the operation of the processor according to the control program stored in the HDD 111 . However, the control unit 100 and the like can also configure the determination unit 105 and the prohibition unit 106 by hardware circuits, regardless of the operation according to the control program by the control unit 10 .

The determination unit 105 determines whether or not the search expression includes a predetermined character string (for example, INSERT, UPDATE, and DELETE that are SQL syntax) that enables database editing. For example, when the operation accepting unit 101 accepts an instruction from the user corresponding to the selection button B31 labeled “Update” shown in FIG. Whether or not the predetermined character string is included in the SQL syntax (for example, the search expression displayed in the display area E2 shown in FIG. 5B) as the search expression accepted by the unit 101 to judge whether

The prohibition unit 106 prohibits storage of the search formula determined by the determination unit 105 to include the character string in the search formula storage unit 113 .

Allowing unrestricted authoring of SQL syntax would allow editing of the database, which is undesirable. Therefore, storage of search formulas containing character strings such as "INSERT", "UPDATE", and "DELETE" that allow operations such as addition, update, and deletion of data is prohibited.

The present invention is not limited to the configuration of the above embodiment, and various modifications are possible. Further, in the above-described embodiment, a multi-function machine, which is an image forming apparatus, is used as an embodiment of the electronic apparatus according to the present invention, but this is only an example, and the copying function, printer function, scanning function, Other image forming apparatuses having a facsimile function or other electronic devices may be used.

Further, in the above embodiment, the configuration and processing shown in FIGS. 1 to 12 are merely one embodiment of the present invention, and are not intended to limit the present invention to the configuration and processing.
